Pintajännitys

Pudotimme 75 naulaa pieneen vesilasiin, ennen kuin vesi alkoi tulla yli…Lasi oli alun alkaen piripinnassa!Huomioi: Veden pinta!!!

Surface tension

First we filled a glass with water full to the brim. After that we guessed how many nails could we drop in before the water starts to drip. Then we started to carefully drop nails in one by one. We managed to drop 75 nails before the water started to drip.

Look at the surface!!!!

A cheap ”water treatment plant” – Halpa vedenpuhdistamo

Mix some dirt with water. Place a tissue paper to the water and the other end to an empty glass. Observe what happens!
